To aZZ whom it'mzty concern:

Be it known that we, THOMAS WATERS WAILES and GEORGE FREDERICK MAsoN,subjects of the Queen of Great Britain, residing at Cardiff, in the county of Glamorgan, England, have invented certain new and useful Means for Carrying Water or other Liquid Ballast or Cargo in Steamships or other Vessels, of which the following is a full, clear, and exact description,and for which we have made application for patent in Great Britain, dated the 4th day of December, 1899.

The object of this invention is to provide means for carrying water or other liquid ballast or cargo in the between-decks or high above the bottom of ships holds in steamers or sailing vessels.

In order that our invention may be clearly understood, we will describe the same by the aid of the accompanying drawings, in which- Figure 1 is a longitudinal section, and Fig. 2 a plan, of part of a vessel, showing one method of carrying our invention into effect. Fig. 3 is a cross-section of Figs. 1 and 2, and Figs. 4, 5, and 6 are plans representing slight modifications.

In the arrangements represented at Figs. 1 to 4, (1 represents the sides of the vessel; (9, the upper deck; c,the between-deck, and d the space in the double bottom to contain water ballast.

In carrying our invention into effect we construct fore-and-aft bulkheads e c, one on each side of the main and upper deck hatch f, from the hold-bulkhead 9 forward of hatch f to the hold-bulkhead g aft of said hatch, thus forming a trunkway to hold underneath.

In the arrangement shown at Figs. 1 and 2 thwartship bulkheads h h are fixed at the ends of the deck-hatch f between the foreand-aft bulkheads 6, thus forming tanks it at the ends of the hold-hatch, While thwartship bulkheads jj are fixed between the foreand-aft bulkheads e e and the sides of the vessel, thus forming tanks k is on each side of the hold-hatch f. Water-tight removable doors h are fitted to the bulkheads h h to afford access to the tanks '1: 7 when the latter are used for ordinary cargo. Access is afforded to the tanks 7c, respectively, by a hatch k arranged partly over each pair of tanks in k and at each side of the hold-hatch f. The tanks 2' 1; may also be provided with hatches.

In the modification shown at Fig. at only two large tanks 7.0 are shown, the tanks 'it' being dispensed with. Each of said tanks 10 extends from bulkhead g to bulkhead g and from a fore-and-aft bulkhead e to the side of the ship. In this case water-tight removable doors 6 can be fitted, if desired, to the bulkheads e e to afford access to the tanks le when the latter are used for ordinary cargo. Access is also obtained to the tanks 70 through tan k-hatches 70 the whole of the trunkway inclosed by bulkheads e 8 being open to the lower hold.

In the modification shown at Fig. 5 the cen- .ter trunkway does not extend beyond the limits of the hold-hatchf, and instead of using two fore-and-aft water-tight bulkheads e e, as in the forms shown at Figs. 1 to I, a foreand-aft water-tight bulkhead e* is fitted at each end of the hold-hatch trunkway and continued to the hold-bulkheads g g. Tanks k are thus formed on each side of the hatch f, which extend from bulkhead g to bulkhead g and partly across the ends of the hatch f. Access to the tanks 70 can be obtained by means of the hatches k and movable watertight doors 6', as in the modification shown at Fig, 4E, if required.

In the modification shown at Fig. 6 the tanks k and hold-hatch f are of similar construction and arrangement to those of the modification shown at Fig. 5; but the hatchways 10 instead of being formed separately at the sides of the hatch f, are formed in the center of the ship as a continuation of the trunkway-hatch f.

The above constructions of tanks can be applied either to the main and upper decks, the main and orlop decks, or the upper and bridge decks, and any or either of the above arrangements can be adapted so as to include a second betweemdeck or bridge-deck, the trunkways and hatches being made to suit.

The various fore-and-aft and transverse bulkheads forming the several tanks are connected water-tight with the decks above and below the same, and the tank-hatches are covered with water-tight removable covers.

By the means above described water or Z, connected with a chamber m, into which the pipes 7, connected with the various tanks, leadyand such chamber m isfitted with valves 01 to open or close the communication between such pipes n and thechamber m, so as to enable one or more of the tanks to be filled'at' a time.

valves through the ships side above the waterline or below, if necessary, or the water bal last can be made to run'from the tanks through pipes into the water-ballast space (1 in the vessels double bottom.

The tanks can be filled with liquid cargo 1.' In a ship, the combination of a hull, an I upper deck, a between-deck arranged from side to side of the hull, aholdfor cargo below such between-deck, a trunkway from the deck to the hold, a number of tanks arranged around such trunkway, and water-tight doors arranged in the sides of the trunkway, substantiallyas set forth.

2. In a ship, the combination of a hull, an upper deck, a lower deck, a hold for cargo below such lower deck, a trunkway from the upper deck to the hold, a number of tanks arranged around the trunkway between the two decks, water-tight doors in the sides of the trunkway, and a hatch arranged above The tanks may be emptied of their Water-ballast by valves, cocks, or non-return,

each tank, substantially as set forth.

3. In a ship, the combination of a hull, an

"upper deck, a lower deck, a trunkway connecting the upper and. lower decks, fore-andtight doors arranged in the sides of the trunkway, and a hatcharranged above each tank, substantially as set forth.
